Answer:
The specific gravity of kerosene is 0.82
Step-by-step explanation:
Let
x -----> the weight in grams of a cubic centimeter of Kerosene
y ----> the weight in grams of a cubic centimeter of water
z ---> the specific gravity of a substance
so
![z=\frac{x}{y}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![x=0.82\ g\\y=1\ g](https://tex.z-dn.net/?f=x%3D0.82%5C%20g%5C%5Cy%3D1%5C%20g)
substitute the values
![z=\frac{0.82}{1}=0.82](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B0.82%7D%7B1%7D%3D0.82)
8=12-8x
-4=8x
-4÷8=8x÷8
-0.5=x
Hi again Jordan, plug into the equation I just answered. Answer: y = 2x + 9
June has 30 days
so 70% of 30 were sunny
0.70(30) = 21 days <==
